@SometimesLovely @SecurityWriter afaik, it's not necessarily a matter of "denying credit", but allowing for peer review.
In theory, all statements are either:
- trivially verifiable by virtue of being assumed knowledge;
- novel contributions which are fully justified in the produced work itself; or
- prior art, regardless of who it was that produced the art (including yourself).
In the first two cases, no references are required because they wouldn't make sense. In the last case, however, references are always required because otherwise how do you know where that statement came from? How can you assess its veracity without a trail to follow?
Otherwise, one can make novel claims and not be questioned on it because "it might be from their prior work".
